Formation: Palestine Sandstone
Formation Depth: 1848’
Prior Production: 0 BOPD
After Stimulation: 12-15 BOPD

In May 2000, a well in Posey County, Indiana, with no production whatsoever was readied for abandonment. An attempt to recover the casing failed. Instead of proceeding with abandonment efforts the well was stimulated with a 6 foot GasGun in a last ditch effort. The cased hole tool was placed at a depth of 1848 feet in the Palestine sandstone formation. Production of 12-15 BOPD was achieved.

Formation: Cypress Sandstone
Formation Depth: 2425’
Prior Production: 1 BOPD
After Stimulation: 18 BOPD
After 2 months: 15 BOPD

In January 2000, another oil well in Posey County, Indiana, was stimulated with an 8 foot GasGun. This well is a cased hole completion in the Cypress sandstone formation at a depth of 2425 feet. Production increased from 1 to 18 BOPD, but also made 200 BWPD. The well was later hydraulically fractured, and since the GasGun had already broken down the formation it took only 900 psi pressure rather than the usual 1400 psi for this location.

Formation: Tar Springs Sandstone
Formation Depth: 2206’
Prior Production: 0 BOPD
After Stimulation: 40 BOPD
After 4 months: 5-8 BOPD

In October 1999, an oil well in Posey County, Indiana, was stimulated with a 4 foot GasGun. This well is a cased hole completion in the Tar Springs sandstone formation at a depth of 2206 feet. There had not been any production from this well prior to the stimulation, and the well produced 40 BOPD and no water after the stimulation. The lack of any water production is significant since hydraulic fracturing in this location typically results in large amounts of water. After four months, production leveled off at 5-8 BOPD.

Formation: Hardinsburg sandstone
Formation Depth: 1766'
Prior Production: 1.5 BOPD
After Stimulation: 8 BOPD
Sustained: 8 BOPD 

In October 1999, an oil well in Vanderburgh County, Indiana, was stimulated with a 6' GasGun. This well was completed open hole in the Hardinsburg sandstone formation at a depth of 1766 feet and had been previously shot with nitro. Production increased from 1.5 to 8 BOPD after the treatment and held steady at that level for four months.
